1. Introduction
Since the Rio Earth Summit in 1992, many studies have
concentrated on environmental issues in the tropics, which have
positively influenced national environmental policies (Glicken,
2000; Benjaminsen, 2001). However, environmental degradation
continues to be a major ecological concern in tropical countries,
where population growth and food production exert increased
pressure on the ecological system (Nagendra et al., 2004; Wright,
2005; Etter et al., 2006; Pacheco, 2006). Thus, monitoring land use
dynamics is essential to tune management strategies that enable a
balance between production and conservation. For the assessment
of the land use/cover changes, remote sensing data play a major
role with their ability to provide quantitative information on the
spatial dynamics of land cover from different time periods (Tekle
and Hedlund, 2000; Tottrup and Rasmussen, 2004; Deng et al.,
2006; Mottet et al., 2006). This technique contributes greatly to a
global understanding of environmental processes, but analysis at
the local scale is more complicated. Finer scale studies in the
Sudano-Sahelian zone reveal the complexity of land use situations,
which are difficult to predict (Warren, 2002; Wardell et al., 2003;
Burgos and Maass, 2004).
Since the 1970s, recurrent drought in Burkina Faso has
intensified the internal mobility of people towards the southern
and western parts, which have favorable environmental conditions
(Boutillier et al., 1985; Henry et al., 2003; Ouedraogo, 2003; Henry
et al., 2004). Based on satellite images from 1955, 1983 and 1993,
Howorth and OKeefe (1999) concluded that the population
increase due to immigration has not led to environmental
degradation in the southern region of Burkina Faso. However,

Informed decision on the management of natural resources requires an understanding of the complex
dynamics of socio-economic and biophysical factors. This study aimed at exploring theland usechange in
southern Burkina Faso at regional and local levels and the underlying causes of change. The local level
study was conducted in twovillages, Boala and Yale, in Sissili Province. Aerial photos from 1984 and1997
and satellite images from 1986 and 2002 were employed to describe the land use dynamics. The spatial
approach was combined with field data collected in 2003 and 2005 for ground-truth checking and
gathering other relevant data. Semi-structured questionnaire was used for gathering data on socio-
economic factors driving land use changes at local level. At regional scale, the annual rate of change in
forest land, grazingland, galleryforest and cropland was0.4, 0.9, 1.6 and 3.8%, respectively. The size
of croplands increased by 14% in some districts with an equivalent annual rate of conversion to cropland
estimated at 0.6% during 19862002. At the local level, the size of croplands increased from 7 to 14% in
Boala and from 21 to 30% in Yale at the expense of shrinking of forest cover from 78 to 40% in the former
and from 41 to 18% in the latter village. Rural migration (3.3% at regional level, and as high as 97% in Yale
and 9% in Boala) coupled with extensive subsistence farming, large-scale commercial farming, intensivefuelwood extraction andother disturbances were the main factorsdriving landuse change.In conclusion,
the results show that in a decade and half the southern region of Burkina Faso has moved from a sparsely
populated area with subsistence farming to a more complex zone of production characterized by high
competition between different land use types. Integrated management of the natural resources in the
region should, therefore, be given more attention.

Wardell et al. (2003) found that significant deforestation had in
fact occurred during the period 19862001 in western and
southern regions along the Volta River basins. Recently, Braimoh
(2006) obtained a deforestation rate of 11% in the grassland areas
and a degradation of 17% in the woodlands of the northern region
of Ghana for the period 19841999, which has a similar ecological
zone as the southern Burkina Faso. Based on analysis of satellite
images from 1986 to 2002, Ouedraogo (2006) found an annual
deforestation rate of 1% in the Bieha district in Sissili Province of
southern Burkina Faso. These findings led to the formulation of key
questions which guided this study: (a) what is the current trend in
land use in the study area? (b) How can the situation observed at
the local scale improve understanding of observations at the
regional (orsub national)scale? (c)Whatare thedrivers of land use
change? To answer these questions, changes in land use were
quantified based on multi-temporal spatial data at different scales
over a 16-year period combined with field-based observation and
information gathered from farmers. We presented several maps
that depict the current change in land use, analyzed the impact of
the change in farming systems on the condition of the forest
ecosystem and recommended strategies for natural resource
management.
2. Materials and methods
2.1. Study area
The study was carried out in Sissili and Ziro Provinces, which
are located ca. 160 km from thecapital (Ouagadougou) in southern
Burkina Faso (1l8020128000 N and 01830028800W), West Africa
(Fig. 1). The study area is characterized by low relief with an
average altitude of 300 m a.s.l. and consists primarily of settle-
ments, cultivated lands, open savanna woodlands, and small areas
of deciduous forests. The forest vegetation includescommunity (To
and Boura) and State protected forests (Sissili classified forest,
Kabore Tambi national park, Cassou forest exploitation zone).
According to Fontes and Guinko (1995), the flora of the region is
dominated by perennial grass species such asAndropogon ascinodis
C.B.C.I, A. gayanus Kunth, and Schizachyrium sanguineum (Retz.)
Alston, which constitute the open savanna. The ligneous species
such as Afzelia africana Smith ex Pers., Khaya senegalensis (Desr.) A.
Juss. and Pterocarpus erinaceus Poir. are also important fodder
species. The occurrence of scattered tree species, such as Vitellaria
paradoxa Gaertn. f., Parkia biglobosa (Jacq.) R. Br. ex G. Don. and
Tamarindus indica L., on croplands is also a common feature in the

study area. This area belongs to the Sudanian or south-Sudanian
zone according to the phyto-geographical zoning established by
White (1986) and Guinko (1984), respectively. The mean (S.E.)
annual rainfall for the years 19952000 was 859.20 31.98 mm and
the number of rainy days per annum was 53.40 2.54. The average
annual temperature is 27.1 8C, with a maximum average monthly
temperature of 31.7 8C in April and a minimum average monthly
temperature of 25.3 8C in August. The population is constituted of a
native ethnic group, Nouni, and migrant group mainly Mossi
(originating from the centre and northwest of Burkina Faso) and
Fulani (originating from northern Burkina Faso). The average
population density is 28 inhabitants/km2 in both Sissili and Ziro
Provinces. The farming system is characterized by traditional
subsistence farming and cultivation of cash crops (cotton, cashew
tree) as well as intensive fuelwood extractions and ranching.
2.2. Land use mapping
The assessment of changes in theland usewas made at regional
and local scales. For regional scale study, two satellite images from
1986 and 2002 were visually interpreted and processed to map
land cover changes. The basic data source was Landsat satellite
images (TMand ETM+):Path195 andRow 52 from November1986and October 2002, with 30 m spatial resolution. Administrative,
topographic and forest maps obtained from the Institute of
Geography andother sources (Kargougou, 2001; Ouedraogo, 2002;
Yameogo and Ramde, 2004) were also used during land use cover
change analysis. The spatial data were further checked for ground-
truth on 58 plots located by a GPS. Canopy coverand canopyheight
were used as criteria to define the woody vegetation units as
follows:
A forest as woody vegetation with canopy cover >40% and
canopy height >5 m
A woodland as vegetation with canopy cover between 15 and
40%; canopy height >5 m
A gallery forest as a stripe of woody vegetation occurring alongthe main riverbank.
To assess the land use dynamics at a local scale, two villages,
Boala and Yale, from Sissili Province were selected. The two
villages differ in the level of farming and in the proportion of
migrant population. To analyze the land use dynamics, aerial
photographs from 1984 and 1997 and a satellite image from 2002
were visually interpreted. The photographs were provided by the
Institute of Geography in Burkina Faso (viz. Mission 84067B Po
1984, scale 1:50,000; Mission 97158B, Sissili 1997, scale 1:20,000).
A field survey was conducted in 2004 to collect ground-truth
information based on 91 plots in Yale and 66 plots in Boala. The
land use descriptions were based on the nomenclature from the
Land cover map of Africa (Mayaux et al., 2004). Four land useclasses were identified for visual interpretation: forest land (a
mosaic of woody vegetation), cropland (land currently under
cultivation and fallows), grazing land (tree and/or shrub savanna),
and gallery forest (a stripe of woody vegetation along the main
riverbank). The mapping was done using GIS tools in Arcview 3.3.
2.3. Drivers of land use change
To further understand the land use dynamics, we gathered data
on factors that could be the underlying causes of land use change,
such as human population, farming system, disturbances to the
different land use types and infrastructure development. At
regional level, data on the population density were drawn from
the national census reports (INSD, 1989, 1998; MATD, 2005) while
local census was conducted in the two villages in October 2002 to
obtain demographic information for the purpose of this study. To
characterize the farming system, farmers were interviewed about
their farm conditions such the length of cultivation time, the type
of crop cultivated, farming techniques, as well as the land tenure
issues and ownership. To assess disturbances in the forests, a
systematic stratified sampling design was applied where the
protected and non-protected forests within a village were
demarcated first, and then systematically sampled by laying
circular plots (55 m radius) on grids. Due to a late acquisitionof the
satellite image from 2002, the sample plots were delineated based
on a map drawn from the 1997 aerial photograph. In Yale, the plots
(91) covered 0.9% of the protected area of the village, and the same
in the remaining non-protected area. In Boala, the plots (66)
represented 1% of the total area of the village. The assessment
included number of stumps of trees cut for fuelwood and local
construction, number of trees pruned for animal feed, number of
trees uprooted by elephants and the percentage of the plot with
indicators of grazing (animal trails, hoof print and herbage
removal). With regard to infrastructure development, we calcu-
lated the road networks at regional and local scales directly from
the maps.
2.4. Data analyses
After each land use type was delineated, its area and proportion
of each land use cover to the total area was computed. The change
in each land use type during the study period was calculated as the
ratio of the difference in area between years to that of the initial
year. This change was further divided by the time interval to get
the annual rate of change. The annual rate of conversion to
cropland was calculated as the difference in proportion of
croplands between years divided by the time interval. Data on
farm attributes were analyzed using descriptive statistics while
information from interviews and field assessment was summar-
ized and presented.
3. Results
3.1. Land use dynamics at a local scale
The trend of land use change was similar between the villages,
although the magnitude of land use change differed. In Boala, the
proportion of cropland doubled while the grazing land tripled
during the 16-year period (Table 1A and Fig. 2). Forest land was
decreased nearly by half in 2002 compared to its coverage in 1984,
while the size of the gallery forest didnot change much. In Yale, the
size of crop and grazing lands increased by 9 and 18% in 2002

compared to thesizes in 1984, while theforest land and the gallery
forests declined by nearly 50%(Table 1B and Fig. 3). At a local scale,
the annual rate of conversion to cropland was estimatedas 0.4% for
Boala and 0.5% in Yale.
3.2. Land use dynamics at the regional scale
At the regional level, the various land use types included
extensive grazing areas, pastoral management unit, subsistence
and commercial agriculture, conservation forest, and production
forest mainly for fuelwood extraction (Fig. 4). The actual size and
proportion of thedifferent land usetypeschangedduring thestudy
period. In 1986, the grazing land had much higher proportion of
the total regional area than other land use types while the size of
croplands was substantially high after 16 years (Table 2). The size
of other land use types decreased during the study period;
particularly the decrease was more notable in the gallery forest
and grazing land. Interestingly, the annual conversion rate to
croplands varied among districts within provinces. In Ziro
Province, the lowest conversion rate was observed in Cassou
and the highest in Bougnounou (Table 3). In Sissili Province, the
lowest and highest conversion rates were observed in Silly and

Niabouri districts, respectively, while no conversion was noted in
Nabielianayou.
3.3. Drivers of land use change
There was an increase in population at both regional and local
levels during the study period. At a regional scale, the annual rate
of increase in population density was 3.3% with remarkable
variation among districts within provinces (Table 3). The values
ranged from 0.7% (Bougnounou) to 5% (Sapouy) in Ziro Province,
and from 2.8% (To) to 9% (Niabouri) in Sissili Province. The annual
change in population density showed some correspondence with
the annual rate of conversion to croplands in most of the districts.

At a local level, there was also a similar increase in populationwith
distinct difference in population density between the villages,
where it was lower in Boala than in Yale (Table 4). It was
interesting to note the high influx of people into Yale compared to
Boala, as shown by the high proportion of migrant population in
the former village.
The farming system was characterized by large-scale com-
mercial farming and subsistence farming (mainly in the form of
shifting cultivation). Large scale farming of commercial crops,
such as cashew nuts, maize andbeans,was found in seven districts
within the region with varying land size (Table 5); the highest
being in Cassou (1228 ha) and the lowest in Bakata (120 ha).
Attributes of subsistence farms are presented in Table 6. They
were generally small in size (46 ha/farmer), being put under
cultivation for longer period by migrant farmers who also put
higher labor input than the natives while they both had similar
off-farm activities and farming techniques. With regard to land
tenure issue, 91% of the migrants got access to land through loan

while 86% of the natives received land as a gift from parents and
relatives.
The extent of disturbance on the different land use types
differed between villages (Fig. 5). Cutting for fuelwood and local
construction was common on croplands in Boala while it was
common on grazing lands in Yale. Pruning of branches and grazinginfluence were largely observed on grazing lands in both villages
while elephant damage was disproportionately higher on forest
lands in Boala than Yale. Concerning road networks, we found
317 km of main and secondary roads, which can be used in all
seasons in the region, and 45% of the villages lying within 5 km
radius from the roads. We also found that Yale is situated at a main
road connecting Burkina Faso with Ghana, while Boala is almost
isolated and the only road to access Boala is the 34 km secondary
road and then the 9 km of path unusable during the rainy season
(i.e., JuneSeptember).
4. Discussion
The results from the present study revealed that there was a
rapid land use change both at local and regional scales. At the local
scale, the size of crop andgrazing lands increased at the expense of
shrinking of forest cover with distinct variation in magnitude of
change between villages. This land use dynamics could be driven
by the associated increase in population due to migration
particularly in Yale village, where local migration is dated backed
to the 1975 (personal communication with villagers). Apparently,
the proximity of Yale to the road made influx of people higher than
Boala, which is in line with the important synergetic causeeffect
relation between population-infrastructure and agricultural
expansion on tropical deforestation (Geist and Lambin, 2002).
The increased influx of people to the village is accounted for
increased in cropland, as migrants are involved not only in
subsistence farming but also in cultivation of commercial crops
such as cotton, cashew and beans. Consequently, Yale is nowexperiencing land shortage and most newcomers have to share
land with established immigrants due to the fact that the protected
forest reserve covers 50% of the village land coupled with the
increasing population. The fact that the migrants have user rights
to the land they obtained by loan illustrates the receptivity by the
native population (Nuni) and flexibility of the land tenure, which
has played an important role in the integration of the migrants
(mainly Mossi and Fulani) in the region, as mentioned by Howorth
(1999). However, this local land tenure is characterized by some
restrictions such as precluding tree planting by migrants, which is
considered as a mark of land appropriation like in many rural areas
of Burkina Faso. These restrictions are being contested by many
established immigrants in Yale, who suggest that having lived
there for over three decades they should have certain privileges aslong as there is no claim on land or a clear intention of
appropriation. They also suggest that the development of tree
crops contribute to the improvement of production systems, which
can be profitable for the village as a whole. This restriction on tree
planting could have a negative impact on the land use, particularly
on the diversity of on farm trees. Although the land use right is

somehow flexible for migrant population, there is a prohibition on
a woman to own farm land by the traditional land rights.
The increase in grazing lands in both villages pertains mainly to
the installation of cattle herders on the protected area of Yale in
1997 (the Fulani ethnic group). In practice the installation was
extended to all open access areas of the region. In recent years the
high density of the cattle herds and uncontrolled grazing practices
have increased crop insecurity, and the episodic conflicts between
herders and farmers have become more frequent (Ouedraogo,
2003).
Most of the landuse dynamics issues observed at a local scale is
also reflected at the regional scale. First, there was an increase in
the size of cropland and population density as well as a change in
farming system, mainly geared towards cash crop production. This
increase in population density is associated with a continuous flux
of immigrants, which in turn alters the traditional agriculture
production systems (McMillan et al., 1992; Drabo et al., 2003;
Henry et al., 2003). The important consequence of the population
increase from influx of people was the high rate of conversion to
croplands observed in several districts. The regional rate of
conversion to croplands (0.6%) is twice higher than the national
rate (0.3%) for the period 19902005 (FAO, 2006). Similarly, the
annual rate of change in cropland (3.7%) was higher than thenational rate of 1.4% from 1984 to 1997 as reported by Stephenne
and Lambin (2001). This trend in conversion to croplands was
confirmed by Ouedraogo (2006) who found a rate of 1% for the
same period 19862002 in Bieha district of the studied region. One
important consequence of this conversion is the degradation of
Sissili protected forest in addition to the increasing illegal activities
such as charcoal production, hunting, and bush fire occurring each
year.
The second important factor is the increasing pressure from
grazing. A pastoral zone was established in 1998 within the
protected area to prevent overgrazing problems but the project
was not successful (Kamuanga et al., 2001). Instead, the high
density of cattle led to excessive pruning of fodder trees and
increasing threats to crops due to grazing, thus resulting indeterioration of social relations between herders and farmers. The
third aspect is the land tenure, which is the same for the region in
the sense that all the rural lands of the region are under the hands
of the native ethnic group (Nuni). However, recent studies have
shown that there is an emerging issue of access to forest resources
by migrants in the region, particularly in Bougnounou district
(Zougouri, 2006). At regional scale too, tree planting by migrants is
not allowed and women has norightto own a land. As inthecaseof
most areas in Burkina Faso, our study site (the southern region)
experiences land tenure insecurity, particularly due to increasing
land transactions for expansion of agri-business (Mathieu, 2001;
Bologo, 2004). In general, land tenure issue in the country is still a
subject of contention, as the Land Reform Act of 1984, revised in
1991 and 1996 (Ouedraogo, 2002) seems not to be fully applied.Several factors contribute to a more complex land usedynamics
pattern when studied at a regional scale. One is thevarious types of
resource management systems, which includes traditional sub-
sistence farming of cereal, intensivefarming of cash cropsand local
market crops and new systems of fuelwood extraction, ranching,
agri-business tree planting, protected forest reserve for fauna
conservation and pastoral management. Another factor is a weak
dialogue and/or consensus between the multitude of actors (i.e.,
native subsistence farmers, migrant farmers, migrant cattle
breeders,private actors) on the access to land and/or itsoccupation
(personal communication with local stakeholders). Sometimes,
different types of activities overlap such as the pastoral manage-
ment of grazing activities located in the Sissili protected forest and
the extensive area of fuelwood extraction. The subsistence
croplands are expanding annually and the agri-business occupa-
tions are gradually increasing into the grazing lands. But at the
same time, the density of cattle is increasing in theregion, partially
due to increasing of local herding and mainly due to the
transhumance of immigrant herders. In this area, there is also
an increasing interest in community forest management by the
local populations (e.g., Boura, To, Bori-Nebou and Cassou
exploitations zones), but Ouedraogo (2001) stressed that the
reliability of the fuelwood extraction activities in Burkina Faso is
questionable. In general, the allocation of areas to the different
activities is not always based on a consensus between the different
stakeholders (Ouedraogo, 2002; Stakeholders communication in
2003). This factor is increasing the competition among different
land use types in the region.
Thecomplexityof thecurrentland usedynamicsuggests a need
for integrated management in the region. Successful cases of local
initiatives in other areas of Burkina Faso exist from which we could
learn (Hansen and Reenberg, 1998; Reenberg and Lund, 1998;
Brasselle et al., 2002). Insecurity to access and use of land is often
caused by exogenous factors that are not adapted to the local
conditions (Ouedraogo et al., 1996; Reenberg et al., 1998), but on
the other hand the adaptation of traditional land tenure rights to
the socio-economic context of land use change is important for theimprovement of the natural resource management systems
(Ouedraogo et al., 1996; Reenberg and Lund, 1998; Drabo et al.,
2003; Mwangi and Dohrn, 2007). To this end some important
conditions are needed, which include local rights recognition,
equity in benefits for actors, and consensus on collective choices
(Hermosilla, 2000; Sulser et al., 2000; Ribot, 2001). Resources
management strategies should be built from experience and
lessons, and also need to be based on factual land use ( Castro and
Nielsen, 2001; Sandewall et al., 2001) where understanding of the
various local situations is valuable (Reenberg, 2001).
5. Conclusions
This study on land use dynamics in southern part of BurkinaFaso shows that in a decade and half the southern region has
moved from a sparsely populated area with subsistence farming to
a more complex zone of production characterized by high
competition between different land use types. The land use
change, both at local and regional levels, is moving toward
increased cropland at the expense of destructing the forest
vegetation, mainly due to population increase from immigration,
the dominance of extensive farming systems, and emergence of
commercial large scale farming. The increasing pressure on forests
from uncontrolled grazing, bush fires, highconversion to croplands
as well as fuelwood extraction are all contributing factors to the
decline in forest cover. Integrated management of the natural
resources in the region should, therefore, be given more attention.
To this end, the following recommendations are forwarded: (a)facilitate local dialogue among the various stakeholders to reach a
consensus on land use; (b) regulate the influx of people to the
region, grazing intensity to reduce the increasing pressure on the
forest resources; (c) empowering local communities in manage-
ment and conservation of forest resources; (d) follow-up of the
land use changes in the region, and the methods used in this study
can be seen as a potential tool for such monitoring.
